## Description

Cisco Quantum Research is seeking a skilled Principal Hardware Engineer to support our Quantum Experimental Team in a role that is central to the physical realization of Cisco's deployable quantum hardware platforms.

 * You act as the primary technical authority responsible for delivering integrated, rack-mounted quantum systems directly to customer data centers and research facilities, directly driving customer satisfaction and site-acceptance timeline success.
 * You will unify disparate engineering domain outputs-including precision control electronics, RF/microwave distribution, thermal management, optical/photonic routing, and fiber management-into a cohesive, manufacturable, and serviceable rack architecture.
 * You will serve as a critical link between the scientific research team and the program management function, ensuring that hardware assembly and test activities are performed with precision.
 * Architect scalable, manufacturable rack solutions by integrating electrical, RF/microwave, thermal, optical, and fiber-optic subsystems.
 * Lead the design, integration, and deployment of rack-level quantum systems for customer data centers and research environments, including EIA-310-compliant rack infrastructure, PDUs, UPS integration, grounding, electrical isolation, thermal management, and environmental monitoring systems.
 * Ensure compliance with global electrical and safety standards, includingUL, CE, and IECrequirements.
 * Optimize system layouts for performance, reliability, serviceability, and efficient cable and fiber management.
 * Collaborate with scientists and engineers to transition laboratory technologies into robust, deployable hardware platforms.
 * Partner with program management to ensure principled execution of assembly, integration, testing, and site acceptance activities.
 * Establish and improve assembly and test processes to support the scaling and delivery of Cisco's quantum computing hardware.
 * Demonstrates outstanding attention to detail and a dedication to quality by consistently producing accurate laboratory records and experimental results.
